Wireless heart monitor

Hi Mari,

You will find the source code for our iOS app at http://www.ti.com/tool/sensortag-sw

Hi Joakim,

Thanks for your reply!!!

I would like to communicate the wireless heart monitor with android mobile devices. The link which you sent directs to sensor tag software. But I need the source code for ECG monitor.

Thanks in advance.

Hi Mari,

The ECG monitor iOS application was developed by a third party, and unfortunately, the source code that you request is not available for distribution.

The communication of the ECG monitor is based in the SensorTag software, so it is definitely a great reference.

Best regards,

Sergio

Hi,

thanks for your reply!!!

i had communicated the  wireless ecg monitor through Android device. i am able to receive the data packets once the notification is triggered. The packets were stored in a buffer and parsing it for each channel and plotting the data. But when i plot the data the curve doesn't looks like p,q,r,s,t wave.it looks like sawtooth wave. May i know the default output from wireless ecg device.

Could anyone suggest me way to draw the ecg wave from wireless ecg device.Thanks in advance.

Hi,

I have received the data in android from a wireless ECG monitor. Could anyone suggest me which filtering technique prefers to use and get accurate data.

Thanks.

 

 

Hi,

Some Quick  Directions Please,

I have communicated the wireless heart monitor with the android device. I have given only the 4 lead input to the ADS1293.But according to design it have 5 lead input. Is 4 lead input is sufficient ?. 

when using 4 lead i have got the ecg data in channel 1 and 2 but channel 3 doesn't have any ecg data. Is there any necessity to process the data after receiving the data android devices.and also suggest me the algorithm to implement the QRS detection.

thanks,

Hello Mari,

I can comment on your ADS1293 related questions, but I would not be able to help with android/sw/bluetooth questions.

The number of electrodes to use is up to you and your design target. You can use 4 electrodes and easily produce data on 2 channels. For example:

Channel 1 (Lead I) = RA - LA

Channel 2 (Lead II) = LL - RA

If you have a fifth electrode, then you can measure an extra ECG signal on channel 3.

As far as not seeing any data on channel 3, can you please verify the value programmed in register 0x2F of the ADS1293? If you would like to read data from three ECG channels the value of this register should be 0x70. If you would like to test it but don't have the fifth electrode, you can configure channel 3 identical to one of the other channels.

Let me know if you are able to see data on channel 3 this way.

Thank you,

Sergio

hi,

thanks for your reply!!

i had an another doubt on BLE cc2541 about data rate. i had change the odr rate according to the data sheet table no 5 to 8.But the samples received in android doesn't match ODR rate. i thing we have change the data rate of ble.

could you suggest me the configuration to change the data rate in BLE cc2541.

I am in need of 320sps. i have set the decimation value R1,R2,R3 in ads1293 to 320 sps. But currently i have received only around 100 samples per channel.

thanks,

Hi Mari,
I am sorry but I don't know how to change the data rate in BLE CC2541. Let's see if members familiar with the CC2541 BLE and SensorTag can comment on this.
